涡轮流量计干扰因素及解决方式

发布时间:2018-01-18 点击:3552次 发布人:admin

涡轮流量计的精度会受到一些外部因素的干扰而影响到测量的精准度,因此,广大客户在使用安装前一定要对涡轮流量计的干扰因素进行及时的排查,以排除干扰因素。

涡轮流量计的干扰因素:

1、介质中一般都有一些杂质,对轴承、轴要产生磨损,使两者间的间隙增大,动件的动平衡被破坏,转速下降,或者脏物进入间隙内,使运动阻力增大,转速下降。这些原因都造成仪表显示值减少,出现负误差,对流体的供方不利。

2、流体温度、压力的变化可能使管道内液体逸出所含的空气或者因管道内的压力低于流体的饱和蒸汽压、使部分液体变成蒸汽,也可能因介质的负压使外面的气体被吸入管道内,这些气体随着被测液体流动,造成仪表指示值增大,出现正误差,对流体的需方不利。

3、流体中的纤维状或粘性杂质附在流量计的转动部分,使转动阻力增大,造成仪表的指示值减少,出现负误差,对流体的供方不利。

4、工作环境比较恶劣,例如,电磁场干扰、灰尘、高温、振动、潮湿等,可能造成涡轮流量传感器的误动作或失灵,直接造成涡轮流量计的示值误差,误差是正值也可能是负值,可能不明显,也可能完全失效。对于上述现象,在比较严重时,能从流程工作状态的对比中发现问题,容易采取相应措施。但是,在问题初期,不采取特殊措施就不能发现问题。

另外,根据涡轮流量计原理和现场工作经验,建议在涡轮流量计安装初期,在流量计的上游、下游各2倍管径的管壁上增设一对测压口,需要时与差压计相连,在工作状态下,记录流量计指示值与差压计指示值之间的对比关系,如果这时一切正常,就把这个对比关系作为以后检查流量计工作是否正常的依据。比如,定期测量这个对比关系,若发现同样的差压计指示值下流量计指示值偏小,则可怀疑到流量计出现故障。

检查流量计的传感器时,可以先检查发讯器。方法是单独取下发信器,输入一个已知信号,对照输出值,即可发现问题。若故障无法短时间排除,可以换上新的。如果不是它的原因,则应当把流量计从流程管线上卸下,进一步仔细检查,对症处理。对于比较脏污的流体或者有可能产生气体的液体。

注:在安装涡轮流量计时,可以在它的上游加装过滤器或消气器、集气器,加强日常维护工作,定期清理过滤器、排除消气器、集气器里的气体或杂物,确保流量计的正常运行。
